From initial MC% assessment through borate treatment and vapor barrier replacement to post-remediation clearance — the full below-grade mold scope in one place.
Assessment
🔍MC% Assessment & Contamination Mapping
Calibrated moisture meter readings at joist and sheathing intervals across your Drewryville, VA crawl space — with visible growth mapped and photographed. Findings documented before any work is proposed. MC% readings inform both the contamination extent assessment and the post-remediation verification target.
Removal
🔨HEPA Removal & Wire-Brush Treatment
Loose and surface mold growth on joists and sheathing is removed using industrial HEPA vacuuming and wire brushing — capturing spore material rather than disturbing it into the airspace. Contained removal prevents spore migration upward through the subfloor assembly into living areas.
Treatment
🌳Penetrating Borate Application
EPA-registered penetrating borate solution applied to all accessible joist and sheathing surfaces after HEPA removal. Borate diffuses into wood fiber over time, providing ongoing inhibition of fungal colonization — including species that may not be visually apparent yet. Borate remains active in treated wood for years.
Structure
🔨Sistering Structurally Compromised Joists
Individual joist assessment for structural integrity. MC readings plus physical assessment of deterioration. Sister framing specified where structural capacity is compromised — documented in written scope.
Barrier
💧Vapor Barrier Repair or Replacement
Ground cover vapor barrier in your Drewryville, VA crawl space — whether torn, undersized, incorrectly lapped, or absent — is repaired or replaced with properly installed reinforced poly, overlapped at seams, and secured to footings and piers. This is often the highest-impact single correction for preventing crawl space mold recurrence.
Systems
🏔Encapsulation vs. Vented Conditioning Assessment
Encapsulation isn't always the right answer. We assess your Drewryville, VA crawl space's specific moisture load, drainage, and soil conditions and recommend encapsulation or enhanced vented conditioning based on what will actually work — not on which option has a higher margin.
